Sleep is critical for mental repair, memory consolidation, and mood regulation. New research shows that even tiny amounts of light from nightlights, hallway glows, or phone screens can interfere with melatonin production and alter brain wave patterns.
Even with eyes closed, the brain detects light, which can slowly affect overall mental health and sleep quality. For truly restorative sleep, bedrooms should be as dark as possible.
Experts recommend blocking windows, powering down screens, and minimizing ambient light to allow the nervous system to fully rest and repair overnight.
